Pores for thought

A Russian-Canadian collaboration could lead to a new generation of porous materials to complement the zeolites. Rather than being based on conventional inorganic salts, however, the materials will be based on peptides. Dmitriy Soldatov and Igor Moudrakovski of the Russian Academy of Sciences in Novosibirsk working with Steacie Institute researcher John Ripmeester have turned to oligomeric peptides as alternative building blocks for porous organic materials. They point out that many peptides have a natural hosting capacity for smaller guest molecules making them perhaps the ideal candidate for creating functional porous materials.
